Hi all...
i have been running eclipse on a windows 2000 box with no issues. Recently
i was debugging..the proble that i am facing is when i am stepping into
the code, if the debugger runs into a 'System.out.println("debug the
debugger");'i get a source not found error..and an option to change the
source.
What do i need to attach so that it works properly.

I suggest filing a bug report with a simple test case to demonstrate the
problem. I'm developing on XP, so I may not be able to reproduce the problem
(and I'm having a hard time understanding what the problem is, from the
description provided).
